A new determination of the (229)Th half-life was made based on measurements of the (229)Th massic activity of a high-purity solution for which the (229)Th molality had previously been measured. The (229)Th massic activity was measured by direct compa

Measurement of sulfur isotope composition (δ34S) by multiple-collector thermal ionization mass spectrometry using a33S-36S double spike

Autor: W. Robert Kelly, Jacqueline L. Mann

Publikováno v: Rapid Communications in Mass Spectrometry. 19:3429-3441

A new analytical technique is described for the determination of δ34S that is comparable to or better than modern gas source mass spectrometry in precision and accuracy, but requires about a factor of 10 less sample. The technique is based on the pr
